Answer:

see explanation

Step-by-step explanation:

the exterior angle of a triangle equals the sum of the 2 opposite interior angles, that is

2x + 4 = x + 60 ( subtract x from both sides )

x + 4 = 60 ( subtract 4 from both sides )

x = 56

exterior angle = 2x + 4 = (2 × 56) + 4 = 112 + 4 = 116°
